To 51,7/ lli/1,0m il; 'liilfl/,l/ cena/'eline Be it known that l., Wurm. Boni'rrn, a citizen of the United States, residing at 'lolodo, in the county of Lucas and State of Ohio, have invented new and useful Improve,- inents in l)ipper-'l`eoth, of which the follow ing is a specification.

'lliis invention relates to dipper-teeth for steam-shovels and the like, the object of the invention being to provide a strong, durable, anthell'ective dipper-tooth and means whereby said tooth may be readily and quickly des tached from the dipper or shovel and reapplied thereto, thus facilitating repairs.

With the. above and other objects in view the invention consists in the novel construe.- tion, combination, and arrangement of parts hereinafter fully described. illustrated, and claimed.

ln the accompanying dra\\'ings, Figure 1 is aside elevation of a dipper-tooth embodying the, present invention shown applied to a dip= per orsliovel, the latter being in section. Fig. 2 is a veitical longitudinal section through they tooth and contiguous portion of the dippor or shovel. Fig. I is a plan View of thel tooth, showing a portion of the shovel in dotted lines. Fig. Lt is a detail perspective view of one of the saddle-plates, and Fig. 5 is asimilar View of one ol' the bifurcated portions of the. dipper-tooth.

Referring to the drawings, 1 designates the niain body of' the improved dip )er-tooth, and l the working point thereof, tfie sii-nie being of any usual or preferred form,

l'n carrying out the present invention thel rear portion of the body of the tooth is slotted, as shown at 3, thereby forming what may be. termed "upper" and "lower" bifiircated portions -l and 5, respectively, the saine being located at a distance from each other equal to or slightly greater than the thick ness of the edge portion of the dipper or shovel. (Shown at ti.) llie bifurcated portions-l and 5 are made of unequal leiigth,the upper portion Ii being of greater length than the lower portion 5. 'lhe upper bifurcated portion Il is pi'ovidedat its i'eareiidwitlia rabbeted tongue 7, and the lower liilureated poi'- A tion 5 is provided with a corresponding rahbeted tongue t4. ltlacli tongue, as shown in ltlg. 5, is of less width than the liiliii'cated portion froln which it projects; and for about i l understood that l, do not linut myself to the oiie-lialf the length of said tongue the lattei is recessed or rabbeted, as shown at tl, thus foiiiiing an abrupt transverse shoulder 1t).

By reference to Figs. 1 and l it will be noted that the rabbets ot' the tongues 7 and 8 are reversel). disposed, or, in other words, the rabbets are formed in the outer surfaces of the tongues.

ln connection with the rabbeted tongues hereinabove described l use a pair of saddleplates,11 designating the upper saddle-plate, and 1". the lower saddle-plate. Each of said saddleplates is recessed or rabbeted, as shown at 13, the forinationof the rabbetjcorresponding in every particular with the formation of the rabbeted tongue associated therewith, so that when the tongue and saddle-plate are brought together they interlock :ind form a splice or scarf-joint, as will be readily understood by an inspection of Figs. 1 and 5. Coupling-bolts 1-1 are inserted transversely and horizontally t hi'ough the overlapping and interlocking portions of the joint, thus anchoring the tooth to the saddle-plates, tho

saddle-plates being in turn pernninently fastened tothe top and bottom ot the dipper or shovel by means of rivets .15`or their equivalent.

The dipper or shovel (j is provided at asuitable pointI with an offset 16, forming upper and lower shoulders 17 and 1S, and the 'top and bottoni saddle-plates 11 and 12 are removing the bolt 1 and also taking out the bolts 1l. 'l`lie scarf-joints between the bil'iircated portions of the tooth and the saddleplates form a secure and reliable anchorage foi the tooth and prevent throwing undue strain on the connecting or fastening bolts. l`lie construction described also prevents the jamming or buckling of the bolts, and thus by keeping' the bolts iii good condition the removal of the same is greatly facilitated.

'llie invention is shown and described in its preferred embodiment herein; but it is to be exact arrangement disclosed, hut i'esei've the IlO portion7 and minor vdetails of construction as may su gest themselves Without sacrificing any of t e principles or advantages thereof.

I claim- 1. A dipper-tooth Comprising upper and lower biurcated portions having?r their extremities rabbeted, in combination with rabbeted saddle-plates.

2. A dipper-tooth comprising rearwardlyextending,r bifurcated portions, and saddlelates with which said hifurcnted portions lieve an interlocked engagement.

3. A dipper-tootli comprisingr hifureated portions, and saddle-plates having a scarl'- jointed connection with said hii'm'cated portions.

44. A dipper-tooth comprisingr hiinrcated portions terminating in tongues, :ind snddleplates recessed to receive said tongues.

5. A dipper-tooth comprising hifurcnted portions having terminal tongues, saddleplates recessed to receive sind tongues, und

i l i fasteners passing through the tongues and saddle-plates.

G. A flipper-tooth comprising rearwardlyextending bifureated portions, saddle-plates with which said hifnrcated portions have an interlocked connection, and clipper-engaging shoulders on said saddle-plates. i

7. A dipper-tooth comprising rearwardlyextending hifnrcated portions adapted to striuldle thedipper, saddle-plates seeuredto the dippernnd having an interlocked engagement with the hifurcated portions of the tooth, and n bolt passing through the bifureated portions ol' the tooth and nlsothrough the dipper.

ln testimony whereof I llixniy signature in presence of two `nitnesses. i
